In the interview at the immigration center on Monday, Ms. Vashukevich said that she had often recorded conversations between Mr. Deripaska and his associates, and that she had 16 to 18 hours of recordings, including conversations about the United States presidential election.

“They were discussing elections,” she said. “Deripaska had a plan about elections.”

But, she added, “I can’t tell you everything.”

Some of the conversations were with three people who spoke English fluently and who she thought were Americans, she said.

The funniest thing I've read on Twitter in a long time was someone observing the irony of a woman named Nastya being the one to potentially take down Trump. I'm skeptical of her claims (because I think she'd be dead already if she has what she claims to have), but one can dream.

I think it's more than appropriate to be skeptical. If this is a planted source and the recordings are talked up, aired, then proven by the Deripaska/Russian sources to be incomplete or fabricated it'd be a real slam to the broadcasting parties' credibility.
